Canberrans could be waiting months to have their hail damaged cars repaired as panel beaters have been inundated with calls.
The Dent Brothers, a car repair business in Fyshwick, had received about 250 assessment and quote requests after the storm hit on Monday, business owner Isaac Dunn said.
Mr Dunn said the business would be repairing damaged cars for at least the next year. Quotes had already ranged from $1500 to $30,000.
"We're just trying to get as many claims assessed as possible and then start booking in people gradually," he said.
"This isn't something that can be rushed because when you rush things of this nature you can start having issues with quality control."
The storm, which resulted in a record number of calls for the ACT State Emergency Service, had been the worst Mr Dunn had seen in his 10 years of business.
"It hasn't been common to see this across Australia but it is definitely getting worse, there's no doubt about it," he said.
"The hail is getting bigger so it's worrying."
In north Canberra, another business said it was expected to be working on hail-damaged cars for at least a year as well.
Frank Post of Fuller Brothers Bodyworks in Belconnen said the business had completed about 100 quotes since the storm as of Tuesday afternoon.
He said about 30 per cent of customers so far had glass damage as well as dents to panels. The business would work to fix glass damage as a priority in order to get cars back on the road.
The average quote was about $10,000.
Interstate repairers are expected to come to Canberra to deal with the backlog of damage.
It comes as the Insurance Council of Australia will expedite claims from the hailstorm. It said more than two-thirds of claims made so far have been car-related.
GIO spokesman James Spence said the company would establish a hail assessment centre in the coming days.
"The centre is designed to quickly assess and triage all hail-affected vehicles so we can make the repair process as seamless and efficient as possible for our customers," he said.
"We will have both assessors and specialist repairers on site to assess vehicles and determine the best method of repair, so we can get the claims process moving as soon as possible."
Mr Spence said the most impacted areas, based on claims, were Acton, Barton and Macgregor.
"As with most hailstorms, we are seeing dents and smashed windows on vehicles and damage to roofs and skylights for homes," he said.
